How To Pass Arguments From Javascript To As3 Using External Interface

I found how to call actionscript from javascript, but I need to pass some arguments too (dynamic),how can I do this? TIA.

Solution 1:

Please, try this:

ExternalInterface.addCallback("sendMsg", generateMsg);

function generateMsg(str):void {
    trace(str);
}

JS:

msg = "";
functionsetMsg(myMsg) {
    msg = myMsg;
    SendDataToFlashMovie(myMsg);
}

Solution 2:

In my experience you have to call the function on the flash object.

I use the following javascript function to get the flash object

functionGetSWF(id) {
    if (window.document[id] != null)
        if (window.document[id].length == null)
            returnwindow.document[id];
    elsereturnwindow.document[id][1];
    elseif  (typeof(document[id]) == 'undefined')
        return $('#'+id)[0];
    elseif (document[id].length == null)
        returndocument[id];
    elsereturndocument[id][1];
}

then call the function as follows

var flash = GetSWF('idOfSWF');
if (typeof flash.sendToActionScript === 'function'){
    flash.sendToActionScript(yourObject,orParameter);
}

the AS3 would look like follows

if (ExternalInterface.available){
    ExternalInterface.addCallback("sendToActionScript",receivedFromJavascript);
}
functionreceivedFromJavascript(myObject:Object,myParameter:String):void{
    // Do something
}

Hope this helps.

EDIT:

Just noticed that I have a small usage of jQuery in the GetSWF function. I'll take a look and try and remove that. (Its the line return $('#'+id)[0];)
